Boto3 Retrier Configuration¶
Prowler's AWS Provider uses the Boto3 Standard retry mode to assist in retrying client calls to AWS services when these kinds of errors or exceptions are experienced. This mode includes the following behaviours:
- A default value of 3 for maximum retry attempts. This can be overwritten with the --aws-retries-max-attempts 5 argument.
- Retry attempts for an expanded list of errors/exceptions:
# Transient errors/exceptions
RequestTimeout
RequestTimeoutException
PriorRequestNotComplete
ConnectionError
HTTPClientError
# Service-side throttling/limit errors and exceptions
Throttling
ThrottlingException
ThrottledException
RequestThrottledException
TooManyRequestsException
ProvisionedThroughputExceededException
TransactionInProgressException
RequestLimitExceeded
BandwidthLimitExceeded
LimitExceededException
RequestThrottled
SlowDown
EC2ThrottledException
- Any retry attempt will include an exponential backoff by a base factor of 2 for a maximum backoff time of 20 seconds.
